Problem

CHARON cannot correctly define the total number of available CPUs on multi CPU groups systems (NUMA architecture, etc) - it reports only a number of CPUs found in its first group.

(info) Affected Charon products: Charon-AXP & -VAX all versions for Windows 

Solution

Enable "Node interleaving" from the BIOS (if available) to make the BIOS report the total number of available CPUs (as a part of one consolidated NUMA group) to the operating system.

For example, on HP Proliant servers, the configuration sequence looks like the following:

  1. Boot the server, press F9 and enter BIOS setup.
  2. Depending on the server, the settings could be found in different places.
    1. On a HP ProLiant G8, go to "Advanced Options" → "Advance Performance Tuning Options" → "Node Interleaving", set it to "Enabled".
    2. On a HP ProLiang G9, fo to "Performance Options" → "Advanced performance options" → "Node interleaving" , set it to "Enabled".
  3. Boot Windows.
